The insect prevention of BlackBerry can be realized on the basis of clearing the garden on a quarterly basis, combined with artificial trapping and killing. Clearing the garden can reduce the number of surviving larvae and reduce the probability of insect pests. Artificial trapping can reduce the number of adults and reduce the birth rate of larvae. Both methods are effective for pest control, and they are pollution-free and pollution-free. If there are a large number of pests, it is necessary to spray an appropriate amount of chemical insecticides to prevent the spread of pests. 1、 How to prevent insects on blackberries? Insect prevention on blackberries can be realized on the basis of clearing the garden on a quarterly basis, combined with artificial trapping and killing. Clearing garden is a green and low-cost way to control pests. Before planting blackberries, it is necessary to clear the garden and reduce the base number of pests by destroying the environment where pests grow. The means of clearing the garden mainly include deep ploughing the land, pruning dead branches and removing weeds. The garbage that has been cleaned up needs to be concentrated or buried deeply.
Artificial trapping is the use of traps to kill pests by using their phototaxis. This method is pollution-free and can well reduce the use of chemicals. And the trap can also be made by hand. In the process of use, it should be noted that the appliance should be replaced in time to avoid the reduction of trapping effect and the inability to prevent and control pests. 2、 How to maintain BlackBerry 1. Nutrients: because nutrients have a great impact on BlackBerry flower bud differentiation and fruit expansion, blackberry needs more nutrients in the growth process. Only by absorbing enough nutrients can BlackBerry achieve the best growth state. Nutrients can come from rotten organic fertilizer or compound fertilizer with more balanced nutrition, which can be sprayed in time to promote blackberry fruit setting.
2. Moisture: BlackBerry has different requirements for moisture in different growth periods, and the soil moisture content needs to be adjusted according to the actual situation of BlackBerry. More water is needed during the growth of branches and leaves, while in order to improve the sweetness of BlackBerry at fruit maturity, it is necessary to keep the soil dry. For the healthy growth of blackberries, it is best to choose land with convenient drainage and irrigation. （HeiMeiZenMeFangChong）
